Frodo: No Sam, I can't recall the taste of food, nor the sound of water, or the touch of grass. I am naked in the dark. There is nothing, no veil between me and the wheel of fire. I can see it with my waking eyes!

"How do you pick up the threads of an old life? How do you go back. And then in your heart - you begin to understand. There is no going back. There are some things that time cannot mend; some hurts that go to deep...that take hold..." Frodo to Sam
